ISO 5657 Ignitability Apparatus

The FTT ISO 5657 Ignitability Test Apparatus is manufactured to conform to ISO 5657 and BS 476; Part 13. The apparatus has been designed for testing building materials and composites, but is capable of testing any sample of 165 mm × 165 mm, up to a maximum of 70 mm thick. The test instrument measures the ignition characteristics of exposed surfaces of essentially flat materials and specimens, with a radiant conical heater and an intermittent pilot flame (“dipping duck”). The test results include minimum heat flux for ignition and time to ignition at a particular incident heat flux.
